CST is US Central winter time (early November to mid-March). The rest of the year Chicago uses CDT (UTC-5), one hour later. For Central Time that follows daylight saving time, use CT to MSK. For daylight-time examples, use CDT to MSK.

How the time difference changes

For most of the year, CDT is 8 hours behind MSK. From Nov 1, 2026 to Mar 14, 2027, CST is 9 hours behind MSK.

For most of the year, working hours of 9:00 am to 5:00 pm in CDT correspond to 5:00 pm to 1:00 am (next day) in MSK. At other times of the year, working hours of 9:00 am to 5:00 pm in CST correspond to 6:00 pm to 2:00 am (next day) in MSK.For most of the year, working hours of 09:00 to 17:00 in CDT correspond to 17:00 to 01:00 (next day) in MSK. At other times of the year, working hours of 09:00 to 17:00 in CST correspond to 18:00 to 02:00 (next day) in MSK.

Compare CST time with MSK time, including current local time, UTC offsets, time difference, daylight saving changes, working hours, and shareable meeting times.
